To all wi bin it my mama;- g

Be itknowii that I HARRY LnNosIEoEL, a eitizen'o'f'the United States, residiti at Cincini'fati, county 'of' HamiIton; and i tate of Qhiohave inyented a new and usefulAdding .nd Recording Machine, of which he following is a specification.

This invention relates to adding'and recordin machinesz 4 V In the "recording"operatiolf'of the typesupport thefl type for recordin gf-properly.

For 'this purposeflleach {type-carrier} is prodevices.

vided with an individiialjactuatingdevice,

usually a sprin 'andlthese spriiigs 'are all v illustrating parts of the invention,

energized ateaeh'operztioifof the controlling shaft of the addingi'maehinei Thus,

assuming that the" 'machine" includes nine type-carriers and a separate actuating spring for each type-carrier, allo'fsaid rings have heretofore been energized at "cash of the controlling shaft; whether all of the type-carriers were"operated-b r not: There-f fore, if onl y one5' two' or three/of the typecarriers for instance were operatedithe'i machines have nevertheless required the tensionmg or energizm' actuatln'g all oft operation v 'i the-spring tensionlng devices after they have of all e'f the i springs for awe-carrier's. It is 011- 1 viously undesirable 'lto ten'sion for energizej springs whose} typ'e carriers are not' placed 1n operationfibecause such ufinecessary opwhereas the energy or tension of the springs whose type-carriers are not to operate re mains unchanged.

The object of my invention is 'to provide efficient mechanism for accomplishing the results above mentioned and those hereinafter more particularly set forthyand with the foregoing and other objects in view I have illustrated one embodiment ofmy invention in the accompanying drawings, in which-.

Figure 1 is a. sectional view of an adding and-reeordinghmachine containing the invention." I I 4 Fig; 2 is a plan view showing the location and-arrangement of the spring tensioning Fig.- 3 is a; perspective view more clearly Figi l is a detail view showing 'portions of typ e-carriers inadvance positions and whose;

operation b :Fig.:5 is a somewhatsimilar view showing been 0 carriers; =5 p I By' reference to the, drawings, it will be wrecognizedthat- I have illustrated m invention in a machine containing: di erflntial meclmni'sm substantially like that contained tin-:the; Dalton addin machine; which; :is manufactured under fiubert Hopkins Patent No.ail,039,130 1 dated September 12, 1912.

emtlqn q ire w =ih wo l-db wln theiniachine Illustrated numbersareset required if only""'thenecessary n umber'of springs were placed uli'dertension; and also results in unnecessarily"weakening the springs.

My present invention overcomes the objec-" tions mentioned; I have provide each type-'- carrier with an individual actuating spring and means properly controlled as an incident to operation of the controlling shaft for-tensioning or energizing-the springs whose typecnrriers are required to operate while leaving the springs for the remaining typecarriers normal or without increase ofenergy or tension. It is appropriate to mention that all of the type-carrier actuating springs normally have a predetermined degree of energy or tension and that the energy or tension of thesprings whose typecarriers are to operate is increased'as an incident to operation of the controlling shaft,

up in a laterally movable carriage-1. The

type-carriers 2 are-.pivotally supported by a rock shaft 3 and are controlledin their re- =cording operations by the stops set up in the carriage 1. The type-carriers 2 are cooperaperated to advance the connected type-- a tively associatedwith racks 2 which actuate the addingwheels 2 in adding and clearing operations. The machine-includes a controlling shaft 4 which is a rock shaft and from which a train of connections comprising a link 5 and an arm 6 leads to theroek shaft 3. When any number is to be recorded the same is, set up in the differential mechanism contained in the carriage 1 after which the controlling shaft 4 is turned in a forward direction, thus also turning the shaft 3 by the connections from the shaft 4 comprising the link 5 and the arm 6.

Each type-carrier is formed with a rearwardly extended arm 7 which is connected shoulderfl arranged to engagethe-gnide plate 12 and limit upward movement of the tensioning members. In this way the tensioningmernbefls will'be held in position in which'th'e springs 10- are slightly energized to impa'rt'an initial movement to the correspondin'g type-carrier when the controlling shaft is operated.

My. "nvention further comprises mechanism for actuating: the energizingmembers lrlzisrequ'iredto-energize'thesprlngs of the type carriers which -it is desired to operate, As clearly shown in Fig. 3 two .ar'ms.-15

A link 17 is pivoted toweaohof the extensions 16,-saidlinks being guided in their movements by the "guide plate 12 th'roughwh ich said links extend.- -Ea'ch of the "links 17"i's f0rmed -with; a fon'wardly extended arm 18,: the sa ine being connected with the rear ends of the arms 15sby'retractile sp'rings 19. "rIt -is obvious that the tendency of the springs '19? as toactuate the lower ends'of the-links 15 rearwardly. ,In.

the normal or idle position of themzichine "th e' link's lfifiire' held in theirforward positions bjidamsflO thereo'n contacting with the. 'wells bf the slots in the guide plate 12 through whiehsiiid links-extend.

In thenormal or idle position of the machine the tensioni'ng members are held in proper position in this instance in vertical position, by projections 23 on the type-carriers engaging the upper extremities of said tensioning members. v

The type-carriers are held in their idle positions, and are returned to their idle positions after each operation, by an appropriate device provided for that purpose which, in the form shown, is a bail. As shown the bail comprises a rod 24 supported by the arms 15 under the extremities of the arms 7 -ing crossmember 21.

of the type-barriers, aiid tubularsl'eeve 25 re voliilzil mounted on said rod.

'A'sfii l 'ii'iniflersfiood by refn-hee twFi 1, the" springs 10 eit'tnd upwardly and forvardly from the upper ends of the tensioni'rig'm'inber's II, thus tending to move the tensionins members to inclined positions. such ten ency of the springs 10 to move the tensioning members to inclined positions is resisted by the projections 23 when the typecarriers are in their normal or idle. positions. However, when any of the type-carriers move forwardly to recording positions: the projectionsv 23 are carried away from the tensioning members 11, whereupon the springs 10 connected with thetype-carriers which have moved forward, move. the corresponding tensioning. members to inclined position as shown in Fig. 4, plaqing the shouliders 22 .ofsaid tensioning-members-in postion to be engaged by the cross member 2].

Further movement of the controlling shaftet mov'esthe arm. 6 to the; position shownin Eig. 5,. As before stated thearm 6 t is attached to the shaft 3, which ie a, .rockshaft so that 'said shaft 3,-is turned by the arm '6, Turning of theshaft 3 also lowers the arms lo from their normal or idle positions shown in Fig. 1 to lowerpo- .sitions' shown in Fig. 5, therebyqmoving downwardly the links, 17 and the connect- Th mem r 2 engages the shoulders 22 0f the tensioning members whose -type carriers have :moved forwardly, it being understood that the ten- -si0ning members corrspondingto the typecarr iers which remain stationarynre not en'gagedg by theoross'mernber 21 This is because the 'tensioning membersll corn spondi'ng to the type-carriers which Zrernain i'clleor stationary a're heldingtheir-iveiitical positions by the projections 23' -on the stationary'type-carriers;- s c-that upon; slight downward movementrof the links 17 the shoulders 20 thereon are moved below .the guide plate'l 2,\vhereupo n the lower ends of said l-inl(s-l7-aremoved rearwardlylto, the positions shown in Fig. 4. This rearward movement of the lower ends of the links 17 is caused by the'springs 19 as before stated, andsuch rearward movement is sufiicient to place the cross member 21' rearwardly from the projections 22 of those tensioning members which are heldintheir normal or idle positions by the corresponding idle type-carriers. Therefore, when the linlrs 17 are moved downwardly the cross member-:21 will not engage with the tensioning members corresponding to the idle typecarriers, but will engage with the tensioning members which are connected with the operating type carriers. Downward movement of the links l? is continued until said links are moved to the positions shown in Fig. 5, the tensi ning members ll cor i type-carriers,-

From the foregoing it will be understood that the only springs corresponding to the type-carriers that are operated are energized or placed under tension as an incident to operation of the controllingshaftand its associated mechanism. This'p'reve'nts needless operation or energizing of the springs which are not required to'function duringf the respective operations of the'machine The advantage of this'result-is obvious.

Theinvention is not dependent upon the nism, but may be used with ual success iii-other machines. Therefore, do not restrict-myself to the use oi the invention in a machine possessing any but desire-to claim the ii'iv' entionin it may be successfully employed. 1 I claimj 1.
